As an amusing aside, a little while ago I attended a lecture given by the Friends of the River Wey (the Dorset one).
We leant that one day a lorry trying to cross a bridge built in local stone knocked a large chunk of the parapet into the river.
The FRW among others contacted Dorset Council and were told nothing could be done for at least nine months, not only by queuing the work itself but all the paperwork first- Risk Assessments, etc., etc…
Not long after this, barriers and warning signs mysteriously appeared next to the damage.
By a strange coincidence, this was followed by someone turning up with mortar materials and tools, and a farm tractor with front loader and lifting slings also manifested.
The parapet was back up by the late afternoon, and after a delay to let the mortar set, the barriers disappeared just as mysteriously as they’d appeared…..
Very odd!
